Zusatz zum Patent 242847. 'Addendum to patent 242847. '
Längste Dauer: 10. Juni 1926. .Longest duration: June 10, 1926.
-Die Erfindung betrifft eine besondere Ausgestaltung des Querschnittes der Thermoelementteile des Pyrometers gemäß dem Hauptpatent 242847 zu dem Zweck, die angestrebte Ersparnis im Gesamtquerschnitt zu fördern und die seitliche Verschiebung bzw.- das Herausfallen der isolierenden Einlage i zu verhindern. -The invention relates to a special embodiment of the cross-section of the thermocouple parts of the pyrometer according to the main patent 242847 for the purpose of promoting the desired savings in the overall cross-section and to prevent the lateral displacement or the falling out of the insulating insert i.
Bei der in Fig. 1 dargestellten Form- sind die Elementschenkel α und b als Profile gezogen, zwischen denen ein entsprechend geformtes Isolierstück i liegt; es genügt jeder äußere Zusammenhalt der Teile α und b, um das Herausfallen des Isolierstückes zu verhindem. Wenn also etwa ein durchgehendes Schutzrohr aus Marquardtscher Masse zerbrechen und stellenweise abbröckeln sollte, so bleibt die Zwischenlage i immer noch bestehen. Bei der Querschnittsform nach Fig. 2 sind die Schenkel α und b rohrsegmentartig gehalten, derart, daß sie mit einer eingeschlossenen Isoliermasse zugleich den ganzen Querschnitt zu einem Vollkreis ergänzen. Ein besonderer Vorteil dieser Bauweise liegt auch darin, daß man bei gegebener Masse eine möglichst große Oberfläche erzielt und gleichzeitig die Festigkeit des Gebildes beträchtlich erhöht. Die weitere Folge davon ist, daß das übliche Schutzrohr sehr dünnwandig gehalten werden kann.In the form shown in Figure 1, the element legs α and b are drawn as profiles, between which a correspondingly shaped insulating piece i is located; any external cohesion of the parts α and b is sufficient to prevent the insulating piece from falling out. If, for example, a continuous protective tube made of Marquardt mass should break and crumble off in places, the intermediate layer i still remains. In the cross-sectional shape according to FIG. 2, the legs α and b are held in the manner of tubular segments in such a way that, with an enclosed insulating compound, they also complete the entire cross-section to form a full circle. A particular advantage of this type of construction is that for a given mass, the largest possible surface area is achieved and at the same time the strength of the structure is increased considerably. The further consequence of this is that the usual protective tube can be kept very thin-walled.
In manchen Fällen wird es sogar möglich, auf ein durchgehendes Schutzrohr ganz zu verzichten und sich mit einigen Rohrschellen, wie in Fig. 3 angedeutet, zu begnügen. In dieser Fig. 3 ist ein kreisrunder Querschnitt nach Art der Fig. 2 angenommen. Im weiteren zeigt Fig. 4, daß sich auf einfache Weise Ausdrehungen oder Einschnürungen vorsehen lassen, in welchen die um eine schwache Isolationsschicht gelegten Bandagen Platz haben, so daß eine Vergrößerung des gesamten Querschnittes durch ein aufgesetztes Rohr ganz wegfallen kann.In some cases it is even possible to go all the way to a continuous protective tube do without and be satisfied with a few pipe clamps, as indicated in FIG. 3. In In this FIG. 3, a circular cross section in the manner of FIG. 2 is assumed. In the further Fig. 4 shows that indentations or constrictions are provided in a simple manner in which there is space for the bandages wrapped around a weak insulation layer, so that an enlargement of the entire cross-section through an attached tube completely can be omitted.
